Special Conditions: Honeywell, Bombardier Model BD-100-1A10 Airplane; Electronic System Security Protection From Unauthorized External Access

These special conditions are issued for the Bombardier Model BD-100-1A10 airplane. This airplane, as modified by Honeywell, will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. This design feature is the installation of a system that provides wireless data download capability from the engine electronic control unit to Honeywell cloud-based storage. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
